Subject: [PATCH] Call player spectator target events and improve
|
|
|
|
implementation
|
|
|
|
|
|
|
|
Use a proper teleport for teleporting to entities in different
|
|
|
|
worlds.
|
|
|
|
|
|
|
|
Implementation improvements authored by Spottedleaf <Spottedleaf@users.noreply.github.com>
|
|
|
|
Validate that the target entity is valid and deny spectate
|
|
|
|
requests from frozen players.
|
|
|
|
|
|
|
|
Also, make sure the entity is spawned to the client before
|
|
|
|
sending the camera packet. If the entity isn't spawned clientside
|
|
|
|
when it receives the camera packet, then the client will not
|
|
|
|
spectate the target entity.
